Study the decision, not just the result.

One loop you can reuse

Most strategy advice arrives as an answer. Keep this, remove that, trade here, push there. An answer can be useful, but it does not travel well when the card pool, opponent, or context changes. A method travels. The five-stage decision trace on this page is the method used throughout the library.

Begin with observation because memory edits a match after the fact. Write down the visible board, hand, resources, health pressure, known information, and the few unknowns that could matter. Then name the actual decision. A vague question such as what should I do becomes something testable: should I spend my flexible answer now, or accept damage to preserve it for a more important threat?

Comparison is where coaching becomes study. Describe at least two plausible lines, including what each line gains, what it gives up, and what next turn might look like. Commit to one line for a stated reason. During review, ask whether that reason fit the information available at the time. The final result is evidence, but it is not the verdict.

Five skills, one connected syllabus

The learning library is arranged by when a decision enters a match. Mulligan study asks what your opening hand is trying to make possible. Turn planning translates the current position into competing lines. Resource study distinguishes immediate initiative from material you may need later. Matchup planning asks which role you occupy and what evidence would make that role change. Post-game review closes the loop without confusing luck with quality.

You do not need to read every lesson before practicing. If opening hands feel arbitrary, begin with mulligans. If turns feel rushed, begin with planning. If every loss produces a different explanation, begin with review. Each page uses the same trace, so the vocabulary stays stable while the problem changes.

The archetype reference adds another layer without pretending that labels are destiny. Aggressive, controlling, combo-oriented, and flexible plans are treated as hypotheses about pressure, time, and resources. A real match can force either player to change roles. The useful question is not what label a deck carries, but what job the position demands now.

• Opening decisions: form a keep hypothesis and define its failure mode.
• Turn decisions: compare complete lines, not isolated actions.
• Resource decisions: name what is scarce now and what may be scarce later.
• Matchup decisions: set a role, then identify the signal that would change it.
• Review decisions: preserve the information that existed before the outcome.

Built for a changing game

Hearthstone changes through releases, balance updates, modes, and rules context. That makes a frozen list of best choices fragile. Decision Fieldbook deliberately avoids live rankings, win-rate tables, current deck codes, and card-by-card keep percentages. Official rules and patch notes are used to mark the freshness boundary, not to manufacture a claim about today's strongest strategy.

Every page displays a freshness class and a last-checked date. Evergreen pages teach reasoning that should survive a changing card pool, but they still receive a scheduled review. Mixed pages combine durable teaching with a small amount of time-sensitive context. Historical pages are bounded to public records. Policy pages explain identity, rights, evidence, and corrections.

When a claim becomes stale, the right response is not to hide the date. The claim should be revised, narrowed, or removed. The sources page explains that process and makes the evidence register public. This is a study library, not a promise that a static page has captured the live metagame.

A new library with a visible history boundary

This domain previously represented a podcast catalogued publicly as HearthCoach: Hearthstone Coaching. Decision Fieldbook is not that podcast and does not speak for its former hosts, guests, listeners, or operator. The history section records a narrow public timeline so that an old link is not mistaken for evidence of a continuing show.

No old audio, transcript, episode description, artwork, logo, mailing list, player identifier, or private record is part of this package. Three old episode paths have enough corroborated public metadata for a plain, noindex bridge. The bridge says what record the URL identified and points to the historical index. Other old episode paths and community or commercial surfaces are assigned 410 rather than being redirected to this homepage.

The visual system follows the same separation. It uses an original field-note grid, text, CSS rules, and a structural SVG trace. It does not borrow game art, fantasy ornament, collectible-card forms, or Blizzard product UI. The about page states the full independence and rights position.
